Hair drug test costs approximately $100 - $500, which is certainly more than urine drug tests. It isn?t intrusive at all and is quite reliable, as doesn?t require privacy and makes falsification of the sample impossible. Though, it does not show the recent drug use, but detects drug use that occurred long time ago. All you need for a hair drug testing is 50 strands 1.5 inches long.The effectiveness of the hair drug testing was proved during the testing study of 1823 hair&urine samples: hair drug testing made it possible to detect 124 of drug abusers while urine testing ? only 57. A short-term abstinence from drugs can?t influence the positive drug test results. Moreover, through hair testing it is possible to tell the time of drug use and the duration of the abstinence periods. For example, opiates (codeine, morphine, and heroin) stay fixed and do not migrate along the hair shaft, making it possible to build time line of drug use. But cocaine, quite on the opposite, moves along the hair length. Hair testing can detect such drugs as: SAMHSA-5, Cannabis, Ecstasy/MDMA, Cocaine, Opiates, Methamphetamine, Amphetamine, Phencyclidine (PCP), Benzodiazepines, & Barbiturates.
